Digital permit application gateway
Start with the issuing authority’s own submission lane. A complete application package, accurate valuation, and accessible inspection path are the fastest route through statutory plan review.
Recommended first click
Use the official digital gateway to submit plans, monitor review comments, pay required charges, and request inspections when the permit is issued. If the link is unavailable, use the agency website or phone number on the administrative profile to confirm the current lane.
Typical review lane
Administrative site-plan review: 10 business days after receipt, excluding holidays. A general building-permit review timeline is not published.
Treat this as a planning signal, not a guaranteed approval date. Completeness, corrections, resubmittals, and agency workload control the actual clock.
Verify the parcel is inside this agency’s service area and note whether a city, state, fire marshal, septic authority, or utility district also has approval authority.
Prepare legible plans, site information, project valuation, ownership authorization, contractor information, and any energy, floodplain, zoning, or utility documentation the issuing office requires.
Keep the permit number, approved plan set, correction comments, fee receipts, and inspection results together. Those records establish the compliance trail for the next trade.
Application documents
Before submission, call 865-215-2325 (Building Codes permits and inspections); 865-215-4660 (Fire Bureau permits) if the project involves a change of occupancy, structural alteration, accessory structure, demolition, or work near a regulated environmental feature.
Source trail
Use these direct agency or licensing links to confirm current instructions before you file, pay, or schedule work. External pages control if their information differs from this directory.
Project questions
Knox County Department of Code Administration and Enforcement is the identified county-level authority for this profile. Confirm that the property is in its service area before filing.
Begin with the online permit gateway listed in the application guide. If the portal does not recognize the address or project type, contact 865-215-2325 (Building Codes permits and inspections); 865-215-4660 (Fire Bureau permits).
Administrative site-plan review: 10 business days after receipt, excluding holidays. A general building-permit review timeline is not published.
Use the official permit portal to submit or track applications. For scheduling or changing a building or sign inspection, call 865-215-2325; fire-system inspections use 865-215-4660. The official inspection lookup portal is https://app.prod.cginspectionlookup.knoxcountytn.gov/. The county zoning ordinance states that administrative site plans are reviewed within 10 business days, excluding holidays; that timeline is for site-plan review rather than every permit type.
Knox County’s adopted code chapter identifies the 2018 International Building Code, 2018 International Residential Code, 2018 International Fuel Gas Code, 2018 International Property Maintenance Code, 2018 International Mechanical Code, 2018 International Plumbing Code, 2018 International Existing Building Code, 2018 International Energy Conservation Code, 2018 ICC Performance Code, and 2018 NFPA 101 Life Safety Code, with county amendments and Tennessee State Fire Marshal minimums. The county zoning resolution does not require a written building permit for maintenance or installation of interior finishes in houses, attached houses, or duplexes, agricultural uses and accessory farm buildings, or home gardening and similar uses. Permits are otherwise required before erection, structural alteration, moving, or a change of use of a building or structure; zoning approval may still apply even where a building permit is exempt.
What makes an application complete
Before you click submit, make sure the drawings agree with the site plan, project description, valuation, ownership authorization, and contractor information. If the work changes structure, occupancy, drainage, fire protection, energy performance, or utility demand, describe that scope plainly. Ambiguous narratives create correction cycles and delay the field schedule.
Save the confirmation number, payment receipt, uploaded plan set, and every correction comment. Those records are the backbone of a defensible compliance file when multiple trades or agencies share responsibility.
Submission quality check
Site: address, parcel, access, setbacks, and existing conditions are consistent.
Scope: structural, mechanical, plumbing, electrical, fire, and energy work is identified.
Closeout: inspection contacts and the final approval path are understood before work begins.
